One backup seed. A vault no elliptic-curve key can open, a bunker that fires when the canary dies, and an identity that signs with hashes.
Your vaults, their successors and your identity all come from one 32-byte seed. It is made in this browser and never sent anywhere. Lose it and the vault is gone: nobody can recover it.
Write it down or store the file offline. Then type the last group to prove you have it.

This vault has already signed. Signing again with the same key would make it forgeable, so the only safe move is to send the same signature again. Anyone can send it.
Pick the tokens in your wallet and approve the bunker. Nothing moves today. If the canary dies, anyone can call fire() and those tokens drop into your vault. ETH cannot be pulled: keep ETH in the vault directly.
Your identity is a Merkle root over 32 one-time keys from the same seed. Each post burns one. Anyone can check it with hashes alone.
That leaf already signed. Send the same post again; never sign a different one with it.
